PATENT DIE AND FORMER.

SPECIFICATION forming part of Letters Patent No. 225,047, dated March 2,1880. I

A Application filed November 26, 1879.

To all whom it may concern:

Beitknown that we, CHRISTIAN G. BLUM and JOHN SGHOETILE, both ofOollinsville, Madison county, and State of Illinois, have invented anImproved Die and Former, of which the following is a specification.

()ur invention relates to an improved die and former to improve theswaging, shaping, or forming the metal blanks, plates, or patterns usedin the manufacture of stock-bells.

Our die and former are such as to swage that part of the blankconstituting the barrel of a completed bell to flare outward from theear or shoulder to the sound-bow, and that part of the blank forming themouth of the bell to be a true oval, and otherwise obtaining improvedresults and advantages, all of which will now more fully appear.

Of the drawings, Figure 1 is a perspective of a bell completed from themetal blank swaged by means of our die and former. Fig. 2 is a plan viewof simply the blank prepared to suit our die and former. Fig. 3 is aperspective of the blank after being acted upon by our die and former.Fig. 4. is a longitudinal sectional elevation through die and former,with the blank swaged between said parts. Fig. 5 is a plan view ofsimply the die and its bed-plate. Fig. 6 is a part section and side viewof the die. Fig. 7 is an end elevation of our die, Figs. 8 and 9 being,respectively, a bottom plan and side elevation of our former.

A represents our improved block or die. is the bed-plate. By means ofbolts passing through the bed-piece the die-formin g part of same can besecured stationary. B represents our improved swage or former. 0represents the sheet-metal plate, blank, or pattern to suit' the die.

Our improvements chiefly relate to the fol- I lowing constructivefeatures Our die consists of two similarly-shaped counterparts orblocks,

12 b, leaving betweenthem the open chamber W, to receive the former.Each of the blocks 1) b has also the like shoulders at c 0, upon whichthe blank is first properly seated before using the former. Theseshoulders consist of right: angle faces made to splay from the centeroutward, the lower face or shoulder having its edge at a rounded, all asshown in Figs. 5, 6, and 7.

In the center each block b b has an inverted V-aperture, cl, extendingfrom the top to the bottom face of the swage-chamber. (See Figs. 5, 6.)In these V-apertu'res the ears of the blank fit and remain during theswaging or to suit or mold, with the former, the sheet metal into theform as illustrated in Fig. 3. We therefore flare the walls and bottomof the swage-chamber, as indicated in Figs. 4., 5, 6, and 7. Morespecifically stated, this chamber 1; has its walls at 0 e and bottomface, 6, made not only to splay from the center outward, but, further,to have its said faces, taken in cross-section, so shaped as to be asemi-ellipse or oval, the latter shape being the most prominent at theextreme ends of the said chamber. It is these points, at e e e 0, somade flaring, when the former is used, that impart a corre spondin gflare at thesame points to the blank. (See 9 in Fig. 3.)

B, our swage or former, has the following constructive features, whichare related to those just described as belonging to the swagechamberwhen said parts are operated: The opposite side faces, f, of the formerwe flare from the center outward, the flare being most prominent at f,as shown in Fig.9. The bottom face, f, of the former likewise flaresfrom the center outward to the extreme ends, which have the greatestcurvature at f. The edges of the side and bottom faces of the former arelikewise made flaring from the center to the ends, as indicated at f.(See Fig. 9.). .Atf the former has a recess to suit the riveting of thehanger for the clapper-hook.

' Lastly, we make the die A, at its end marked a0 ac, to have thedie-blocks b b, swage-chamber b wider in cross-section than the oppositeend. Also the former B has one end so made wider than the opposite ends.(See Figs. 5 and 8.) This feature of making the die and its formerlarger at one end is to suit the width at w wof the blank. (See Fig. 2.)When the blank is swaged into the shape shown in Fig. 3, and in the actof bending it into the barrel or bell shape, the small end or width ofthe blank will and by a single blow or pressure to force the 7 blank tothe bottom of the die.

the shape of the blank is fashioned as shown In so doing in Fig. 3.Finally, the blank so shaped is bent together in the bell shown completein Fig. 1.

The blanks can thus be made to assume a new pattern or shape, andconsequently the make of our bell is such as to have a more decidedflare, its mouth a more perfect oval, and the sound of the bell have amore enhanced effect.

What we claim is- The die A, consisting of the side die-blocks, b I),having shoulders at c 0, made to splay from the center outward, andhaving rounded-01f edge at the extreme ends, one pair of said shouldersbeing made wider than the pair "at the opposite end, the sWage-chamber b1ikewise made to splay from center outward, its opposite walls andbottomface and edges made to flare 0r curveoutward' at the points 6 e 6, itschamber likewise having one end wider in cross-section than the oppositeend, in combination with a swage or former, B, having its 25.

side and bottom faces and their edges made 'to have the flares orcurvatures from center outward at the points f f f, and also having itsone extreme end Wider in cross-section than its opposite end, by meanswhereof a sheetmetal blank can be shaped, formed, or swaged in themanner and forthe purposes set forth.

In testimony whereof we have hereunto set our hands.
